Figure 16 Virtual-Flash Emulation Areas of the M32174F4VFP (Replaced in Units of 8 Kbytes)
Note 1: If the same bank area is set in multiple virtual-flash bank registers and the virtual-flash emulation enable bit is enabled,
the corresponding internal RAM area is assigned to either bank register according to the priority FELBANK0 > FELBANK1
> FELBANK2 > FESBANK0 > FESBANK1.
Note 2: When access is made to the 8-Kbyte area (L bank) specified with virtual-flash bank registers 0-2, the internal RAM
area is accessed. During virtual-flash emulation mode, RAM data can read and written to and from both the internal RAM
area and the virtual-flash setup area.
Note 3: Internal RAM area (H’0080 C000-H’0080 DFFF) cannot be used as Virtual Flash Emulation area.
The table below shows Virtual-Flash Emulation Areas of the M32174F4 and M32174F3.

Figure 17 Virtual-Flash Emulation Areas of the M32174F4VFP (Replaced in Units of 4 Kbytes)
Note 1: If the same bank area is set in multiple virtual-flash bank registers and the virtual-flash emulation enable bit is enabled,
the corresponding internal RAM area is assigned to either bank register according to the priority FELBANK0 > FELBANK1
> FELBANK2 > FESBANK0 > FESBANK1.
Note 2: When access is made to the 4-Kbyte area (S bank) specified with virtual-flash bank registers 0 and 1, the internal RAM
area is accessed. During virtual-flash emulation mode, RAM data can read and written to and from both the internal RAM
area and the virtual-flash setup area.
Note 3: Internal RAM area (H’0080 C000-H’0080 DFFF) cannot be used as Virtual Flash Emulation area.
